There is a lot to be said in favour of EMD and IMF. This is known, and I welcome this analysis.
A couple downsides are what seems to be the computations required in real time - someone else alluded to that on another forum. Metatrader is no Excel.
The other thing with using it intraday is that markets go flat during certain periods of the day. A trite example is say the Dow Jones or S&P, which are open for business nearly 24 hours, but during Asian trading hours, and sometimes even into Euro, they can flatline at worst and at best just drift around. So, the envelope may need sufficient time when normal trading resumes to find "equilibrium" and recalibrate.
May also be an issue with currencies, but to a lesser extent.
Clearly not an issue with daily data. This is where this analysis shines.
Similar considerations may also apply to anything requiring a range, eg, fractal analysis.
Kind of on Ehlers topic, I think he did try his hand at something like maxima and minima a while ago - I forget what, can look it up. Was in Stocks and Commodities. I was not convinced he had it right at the time, hence my dismay and lack of details. It has not featured in any of his books.
